Abstract

유전체 블록(1)의 마주보는 단면 사이에, 내주면에 내부 도체(3)가 형성된 공진기 구멍(2,2)이 형성되며, 유전체 블록(1)의 외면에 외부 도체(4)가 형성되며, 외부 도체(4)의 소정의 부위에 입출력 전극(5,5)이 형성되며, 유전체 블록(1)의 일측의 단면 근방에 내부 도체(3,3)를 절단하여 분리하는 홈(11)이 형성되어 있다. 홈(11)에 의하여 각 공진기의 개방단이 단면보다 깊숙한 위치에 형성되어 있다.Between opposite sections of the dielectric block 1, resonator holes 2, 2 having inner conductors 3 formed on the inner circumferential surface thereof, outer conductors 4 formed on the outer surface of the dielectric block 1, Input and output electrodes 5 and 5 are formed at predetermined portions of the conductor 4, and grooves 11 are formed to cut and separate the inner conductors 3 and 3 near the cross section of one side of the dielectric block 1. have. The opening 11 of each resonator is formed at a position deeper than a cross section by the groove 11.

따라서, 유전체 블록의 단면보다 깊숙한 위치에 비용이 저렴하고 정밀도가 양호한 개방단을 형성할 수 있으며, 이에 따라 저가이며 양호한 특성을 갖는 유전체 필터를 제공한다.Therefore, an open end with low cost and good precision can be formed at a position deeper than the cross section of the dielectric block, thereby providing a dielectric filter having low cost and good characteristics.
